There's a tiny kernel, and there are syscalls, because after all the executable is -though ELF- a statically linked executable with a statically linked libc, but that mini kernel only handles very few system calls, and does not provide the full generality of Linux. Yes I shouldn't have said "there's no syscalls", just no generic I/O.
